Myinvention relates broadly to improvements in envelope openers andpaper cutters, and more particularly to combined envelope openers andpaper cutters and paper punches.

It is one of the principal objects of my invention to provide arelatively compact and small device which may be carried in the pocketor handily used about a desk, and which has combined and cooperatingstructure designed to open envelopes, cut or trim paper, punch holes inpaper and the like, and which in addition has means for guiding anddetermining the point at which an envelope or paper is to be cut.

Another object of my invention is to provide a very simple and effectiveoperating mechanism, and to provide means whereby proper adjustmentbetween the rotary cutting blades is obtained to afford a clean, sharpcut. Furthermore, there are no fragile parts likely to become derangedor to get out of order or broken, and the device can be manufactured andsold at a price recommending its use as an economical desk and pocketimplement.

Other and equally important objects and advantages will be apparent fromthe detailed description taken in connection with the accompanyingdrawing, however, a broad interpretation of my inventive concept is notto be assumed from the particularization required to impart a clearunderstanding of the construction, operation, and advantages of myinvention.

In the drawing wherein I have illustrated a In the drawing wherein likecharacters of reference are used to designate like or similar partsthroughout the several views:

The numeral l designates the casing or supporting frame of my devicewhich has an elongated base 2 with side and end walls and in which ispivotally mounted as at 3 a hand operating lever 4, adjoining andcommunicating with the base is a compartment 5 having side and end wallsin which is journaled the shaft 6, shaft 6 is mounted for bothrotational and sliding movement and carries at its end a. rotary cuttingwheel, or rotary blade I, the rotary cutter 1 may be rotationallymounted on the shaftir desired, rather than mounting the shaft itselffor rotation and keying the blade to it. Mounted on a stub shaft 6A isanother rotary cutting! wheel, or rotary blade 8; the proximity of thetwo blades being such that when they are positioned adjoining and inproper contact with each other, a sharp, clean cut will be made throughan envelope or other sheet of material drawn between them.

livotally mounted as at 9 in the frame is a lever l0 having an arm Hpivotally connected to the operating 1ever 4 and connected with theshaft 6 so that pressure on the operating lever 4 causes the shaft toslide or move horizontally. The normal position of shaft 6 is shown inFigures 1 and 4 with the rotary cutters I and 8 spaced from each other.The shaft is held in this position by a coil spring 12. Pressure on theoperating lever moves the shaft against the force of spring 12 to bringthe rotary cutters toward each other and into engagement to make a sharpclean cut through an envelope or sheet of material drawn therebetween.

It will be noted that as the shaft 6 is moved longitudinally, its freeend passes out through the end wall of the base. A keeper I3 with aright-angular guard I4 is provided so that the end of the shaftfunctions as a paper punchthere being an opening I5 in the guard forthat purpose. The shaft 6 therefor serves the dual purposes of rotarycutter support and paper punch.

Mounted in the space l6 between the walls of" base 2 and compartment 5is a guide piece H to determine at what point an envelope or sheet ofmaterial is to be cut. An adjusting nut 18 fixes the position of theguide and is provided with the usual spring tensioning device Hi.

Pressure on the operating lever 4 and consequent movement is translatedinto sliding movement of the shaft 5 through lever I0 against the forceof spring 2, so that holes may be punched in sheets of paper by the endof the shaft. The same operations move the shaft at other times to bringthe rotary cutters I and 8 together with the proper pressure to cleanlyand sharply cut through an envelope or sheet of material drawn throughthe cutters.

While it is believed that the operation, construction, and advantages ofmy invention will be fully apparent from the foregoing, it is pointedout that changes in form, size, shape, arrangement and coordination ofparts may be made,

provided such changes fall within the purview of what is claimed.

I claim:

1. A combined envelope opener, paper cutter and punch, comprising aframe, a slidably mounted shaft carried by the frame, means foractuating the shaft to force an end of the shaft through a sheet orsheets of material to form a punched hole therein, a rotary cuttercarried-onthe other end of theshafft zalsecond rotary-cutter coop:erating with the first cutter to open an envelope passed therebetween,the position of the first cuteter with respect to the second heingdeterminable v by the position of the shaft, and an adjustable.

guide for regulating the point at which an en velope or sheet ofmaterial is cut 1 j 2. A cutting and punching device comprisinga.

-;nected to said shaft and an operating lever, which is pivotallyconnected to said frame, a spring connect ed" tosaid lever to retainsaid actuated means in inoperative position, a fixed rotary cuttercoeparating with. said first rotary cutter, and said frame, and a pairof rotary cutters; 'meansfor**" regulating the position of one cutterwithgrespect to theother cutter, and at the same time regu lating thepressure between 'the cutters including Eslidahle shaft on which onecutter is -mounte'df,

first rotary cutter being movable with respect to the fixed cutter uponmovement of the shaft to adjust the proximity of the cutters to performa clean sharp cut.
